Electric start diesels are unseen around here unless a collector has imported one from the US south.
Rewinding the factory 24V starter for 12V reduces the starter output. For those new conversion kits did they increase the starter motors dia, length or both? To get enough 12V power there has to be larger dia copper windings and more off them.
I looked at my 840's but the electric's have been pilfered off the one. And the other has had a tinker's 12V conversion.
I'll try to remember again tonight to measure the length, dia and find a data plate. Maybe some measuring to see just long and large dia starter motor frame can be crammed in there.
The way those wee Nipenso starters work is rpms. They use permanent magnets of strength that wasn't available years ago.
This allows the current flowing into the motor to do the cranking instead of also having to make the other magnetic pole as well. Less copper losses too.
The armature is beefy and small in dia. This allows it to spin at rpms that would disintegrate a conventional starter. The extra stage of reduction gear drive brings the rpms down and the torque up to crank the diesel.
Starting on one 12V 1000 CCA battery will be hard pressed under the most ideal wiring design and installation. To make 10HP at the starter.
